Troubleshooting Common Problems
Why doesn't the projector turn on?
Solution 1 ► Ensure the power cord is properly attached to the projector and to the power outlet.
Solution 2 ► If the cooling process has not completed, please wait until it has finished then try to turn on the projector again.
Solution 3 ► If the above does not work, try another power outlet or another electrical device with the same power outlet.
Solution 4 ► Check that the battery has remaining power, or needs external power.
Why is there no picture?
Solution 1 ► Ensure the video source cable is connected properly, and that the video source is turned on.
Solution 2 ► If the input source is not selected automatically, select the correct source with the Source key on either the projector or the remote control.
What should I do if the image is blurry?
Solution 1 ► Adjusting the Focus Ring will help correctly focus the projection lens.
Solution 2 ► Ensure the projector and screen are aligned properly. If necessary, adjust the height of the projector as well as the projection angle and direction.
Why is the remote control not working?
Solution 1 ► Ensure there are no obstacles between the remote control and projector; and that they are within 8 m (26 ft) of each other.
Solution 2 ► The batteries may be out of power, please check and replace if necessary.
What should I do if the projector freezes or doesn't respond?
Solution ► Using a paper clip, carefully insert it into the Reset button at the rear of the projector to reset the device.
Maintaining the Projector
General Precautions
- Make sure the projector is turned off and the power cable is unplugged from the power outlet.
- Never remove any parts from the projector. Contact ViewSonic® or a reseller when any part of the projector needs replacing.
- Never spray or pour any liquid directly onto the case.
- Handle the projector with care, as a darker-colored projector, if scuffed, may show marks more clearly than a lighter-colored projector.
Cleaning the Lens
- Use a canister of compressed air to remove dust.
- If the lens is still not clean, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the surface.
- CAUTION: Never rub the lens with abrasive materials.
Cleaning the Case
- Use a soft, lint-free, dry cloth to remove dirt or dust.
- If the case is still not clean, apply a small amount of non-ammonia, non-alcohol based, mild non-abrasive detergent onto a clean, soft, lint-free cloth, then wipe the surface.
- CAUTION: Never use wax, alcohol, benzene, thinner, or other chemical detergents.
Storing the Projector
If you intend to store the projector for an extended period of time:
- Ensure the temperature and humidity of the storage area are within the recommend range.
- Retract the adjuster foot completely.
- Remove the batteries from the remote control.
- Pack the projector in its original packaging or equivalent.
Disclaimer
- ViewSonic® does not recommend the use of any ammonia or alcohol-based cleaners on the lens or case. Some chemical cleaners have been reported to damage the lens and/or case of the projector.
- ViewSonic® will not be liable for damage resulting from use of any ammonia or alcohol-based cleaners.
